BOW-FACING OAR.

SPECIFICATION forming part of Letters Patent No. 745,504, dated December 1, 1903. Application filed July 14, 1903- Serial No. 165,425. (No model.)

To all whom it may concern:

Be it known that I, WLADvs LAPACZ, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Bow-Facing Oars, of which the following is a specification.

This invention relates to an improvement in bow-facin g oars, and it has for its object to provide means to enable an oarsman tooperate the ear, and at the same time face in the direction in which the boat is moving; just the reverse of what'is the casein an oar and oarlock of ordinary construction.

In the accompanying drawings forming a part of this speeification,-Figure l is a top plan view of an ear and oar-lock embodying my invention; Figure 2 is an enlarged plan view showing a portion of the car and oarlock embodying my invention, and Figure 3 is a-longitudinal sectional view.

In the drawings, a designates the gunwale of a row boat, the upper edge of which is covered with a suitable angle iron I). c designates plates secured to the said angle iron. Formed upon the inner ends of the said plates 0 are lugs or cars d, which are vertical to the said plates 0, and also vertical to the upper edge of the gunwale of the boat. The lugs or cars d may be supported in any other suitable manner upon the sides of the boat,-for instance, they may site ends of a single plate secured to the said angle iron as is obvious. Support-ed upon the said cars at is a rod 6 arranged longitudinally of the gunwale of the boat, the said rod being secured in position in the ears by means of nuts f. h designates a support, pivotally mounted upon the said rod 6, and 11 desig- 0 nates pins upon the respective ends of the pin 6.

said pivotal support h In designates the blade portion of an car, and Z designates a socket piece mounted upon the inner end of the said blade portion; and the said socket piece is provided with a boss in through which a perforation 0 extends for. the reception of the pin r1 upon the outer end of the support h;

It will be noted that the blade portion loot the car ispivotally supported upon the said provided with an extension 10 provided with an elongated slot q, the purpose of which will be formed upon the oppo- V The inner end of the socket piece 1 is be hereinafter explained. r designates a socket member orhead secured upon the outer end of a handle portion 3 of the car, the said socket member 0" being pivoted to the pin '5 upon the inner end of the supporting member h in the manner described with respect to the socket member Z. The socket member 0 is provided with an extension 6, the outer end of which is provided with a projection it upon its underneath side and at its extreme outer end, the said projection being adapted to engage within the slot q formed upon the inner end of the extension 19.

The handle and blade portions of the car are secured upon the pins L by means of catches c which are pivotally secured to the respective portions of the oar by means of the screws Normally, the catches are in engagement with the grooves :r in the upper ends of the pins. When it is desired to remove the oar the catches are swung out of engagement with the grooves as, after which the two portions of the oar may be disengaged from the said pins i.

Upon examination of the figures of the draw ings, and especially Figure 1, it will be seen that the portions k and 5 move in the same direction, that is to say, as the handle portion 8 is moved forward to the position indicated in dotted lines in Figure 1, the blade portion is will also move forward to the position indicated by dotted lines in the same figure; and a reverse movement from the dotted line position will bring the portions 1:; and s to the position indicated in full lines in the same figure.

By reason of the fact that the portionslc and s of the oar are mounted upon the pivotal support 71., the blade of the said portion is can be readily dropped into and elevated out of the water in the operation of rowing. It will also be seen that an oarsman can sit in a boat facing the direction in which the boat is moving and readily operate the oar to propel the boat forward.

'I wish it to be understood that various changes may be made in the details of construction without departing from the spirit of my invention.

Having thus described my invention, I claim 1. Inan oar-lock, in combination, asupport pivotally mounted upon the gunwale of the boat and provided with pins upon its opposite ends, and an oar consisting ofa handle portion and a blade portion, the said portions being pivotally and detachably mounted upon the said pins and being provided with extensions which are pivotally connected, and hooks pivoted respectively to the handle and blade portions of the said oar and adapted to engage the said pins to secure the oar upon the said pins.

2. In an oar-lock, in combination, a pivotal support provided with'pins upon its opposite ends, an oar detachably secured to said support, the said oar comprising a blade portion, the inner end of which is pivotally supported upon one of the said pins and which is provided with an extension having an elongated slot therein and a handle portion the outer end of which is pivotally mounted upon the other of said pins and which is provided with an extension having a projection upon its inner end adapted to engage the said elongated slot, and hooks pivoted to the said oar and adapted to engage the said pins to secure the oar upon the said support.

3. In an oar-lock,in combination,plates having ears at their inner ends secured to the upper edge of the gunwale of the boat, a rod supported by said ears, a support pivotally mounted upon said rod, pins secured to the opposite ends of said support, an oar detachably secured to the said support, the said oar comprising a blade portion which is pivotally secured to the outer one of said pins and is provided with aslotted extension, and a handle portion pivotally secured to the inner one of said pins and provided with an extension having a projection upon its inner end which is adapted to engage the slot in the said slotted extension, and hooks pivoted to the said oar and adapted to engage the said pins to secure the oar upon the said support.

In testimony that I claim the foregoing as my invention I have hereunto signed my name this 2d day of July, A. D. 1903.
